The game doesn't use the whole potential of the 3ds. The 3D effect is still pretty nice, but the repetitive gameplay and level design aren't entertaining. If you like dinos you should wait for a price-cut.
Combat of Giants: Dinosaurs 3D looks like a rushed product which does not even tale advantage of features such as the touch screen. The idea of a war between dinosaurs is neat but the developer had to work harder on the overall gameplay.
